Definitions

  • This invention relates to the handling of animals and, in particular, to apparatus for automatic processing of animals as in abattoirs, boning plants, etc.
  • an animal processing line which includes an animal lead up race, capture and stun assembly, and hock and horn removal stations located after the animal has been stuck. The carcass is then ready far manual or automatic dressing and boning operations.
  • an apparatus for automatically processing an animal carcass so as to remove the animal head from the remainder of the carcass comprising a cutting means and including head holding means, the head holding means comprising locating means for locating in use the animal head in a desired position, and clamping means for clamping the head against movement, the apparatus further including stretching means for stretching the neck of the carcass so as to spread the atlas joint, and said cutting means comprising a cutting blade which is selectively movable along a cut line located caudal to the jaw and generally along the line of the jaw and through the atlas joint so as to sever the head from the remainder of the carcass.
  • the locating means preferably comprises a cradle engageable with the head, the cradle being movable generally along the longitudinal direction of the head so as to position the cradle in the desired relative longitudinal position before clamping.
  • the carcass is supported preferably in an inverted position with the spine located beneath the carcass and the head hanging downwardly, the locating means being operative to relatively engage with the back of the hanging head, the locating means including sensing means for sensing the presence of the back of the head upon contact being made with the back of the head.
  • the clamping means is preferably operative to clamp the head cranial to the cut line, the clamping means including a jaw clamp for urging the head into the cradle to locate and clamp the head against movement.
  • the stretching means is preferably operative to move the head holding means relatively away from the remainder of the carcass until there is a predetermined reaction against further stretching of the head away from the carcass.
  • the stretching means may include a reaction sensor mounted to the head holding means, the reaction sensor being located so as to be contacted by the crown of the head whereby upon stretching of the neck the crown of the head acts against the reaction sensor with a force sensed by the reaction sensor.
  • the cutting blade preferably comprises a shear blade movable from the throat region generally along the jaw line, the shear blade being operatively associated with a shear reaction blade carried by the head holding means, the shear reaction blade being located during the cutting operation adjacent the crown of the head and behind the spread atlas joint.
  • the equipment can be thoroughly cleaned and/or sterilized for reuse so as to prevent cross contamination of carcasses.
  • the design of such equipment takes into account the need for thorough cleaning.
  • Manual operations continue to prepare the carcass for head removal, hide removal and evisceration. This may include severing the head hide; removal of the muzzle; recordal of tooth number; removal of the tongue; and complete the clearing of the oesophagus, trachea and arteries from the thoracic cavity.
  • the tongue and then the head may be passed to a separate conveyor to be separately processed.
  • Head removal is an automatic operation utilising apparatus as claimed and described in the underlying Specification.
  • a series of manual operations may be carried out to prepare for aitchbone cutting, hide removal, evisceration and splitting. This may include rumping; mark and strip the tail; remove tail bush; remove the pizzle and erector muscles; clear and pull the rectum and bung (sphincter); and bag the anus.
  • the carcass is preferably suspended by the four legs, inclined head down approximately 30° to the horizontal.
  • FIGS. 1 and 2 illustrate the features of such a mechanism.
  • the first operation of the auto cycle is to operate head holding means 12 to locate and hold the head and position the cutting means 151. This is achieved by the activation of two limit switches 152 and 153 mounted on the cutting means 151.
  • the auto cycle begins the cutting means 151 swings up through an arc until the back of the head 10 is sensed by switch 152. This ensures that the head 10 is in contact with the head locating means 13 shown as head cradle 154.
  • the unit then rises vertically until the backbone is sensed by switch 153, positioning the crown of the head 10 in front of the shear reaction blade 155.
  • the clamping means 14 may operate in two stages:
  • the head transfer clamps 159 lock onto the side of the head 10 to prevent any rocking motion of the head during cutting.
  • the cutting blade 156 and reaction blade 155 co-operate to describe a scissor action with the cutting blade following the line of the jaw 9 to shear the head through the atlas joint. Any suitable means may be used to actuate the blade 156.
  • the aim of cutting close to the jaw 9 is to leave as much saleable meat on the carcass as possible, and minimise the amount of trimming from the head 10 on the head processing line.
  • the head transfer clamps 159 swing the severed head out to transfer it to the head processing line. The mechanism then resets for the next carcass.
  • the head cradle 154 centralises the head 10 for clamping and ensures that the jaw line is approximately parallel with the cutting blade 156.
  • the gap 160 between the guides 161 and 162 prevents the bridge of the muzzle from rotating.
  • Ram 163 operates to raise the unit on arm 166 up guide rails 164 and 165.
  • the cutting means 151 is pivotally mounted on arm 166 at 167 whereby the angle of cutting means 151 is adjustable.
  • a stretching means 15 comprises a ram 168 enabling the captured head 10 to be drawn downwardly so as to stretch the neck 11. Additional rams (not shown) operate the clamps and cutting blade.
